ABSTRACT:
An image processing method is provided for performing false color reduction processing on a color-difference signal acquired after performing color interpolation processing on image data taken in by a color image pickup sensor, wherein the false color reduction processing uses a one-dimensional filter for selecting N (N≧4) pixels which are continuous in a row direction including a target pixel and determines a pixel value of the target pixel from the pixel values that remain when maximum and minimum pixel values are excluded from the pixel values of the pixels selected by the one-dimensional filter. This enables effective reduction or elimination of a false color generated at an edge part by the color interpolation processing.
